What is the purpose of a computer network?

• A. To conduct data backups
• B. To replace single-user systems
• C. To connect multiple computers for communication
• D. To increase system processing speed

Answer: (C)

The purpose of a computer network is primarily to connect multiple computers for communication. This interconnected setup allows users on different computers to share resources, such as files, applications, and internet access, fostering collaboration and efficiency. By enabling devices to communicate, networks also facilitate data transfer and sharing, which is essential for tasks such as remote work, online gaming, and accessing cloud services.

While conducting data backups and increasing system processing speed can be benefits associated with computer networks, they are not the primary purpose of a network itself. Additionally, although networks can provide an environment where multiple users can share resources more efficiently than single-user systems, they do not inherently replace those systems. A network's main function is to promote communication and resource sharing among connected devices, making option C the most accurate representation of a network's purpose.
